abs light comes on sporadically when applying brakes. also feel a pumping sensation in pedal and a noise at same time which causes volt meter to temporarily begin discharging. unknown cause to problem. taking to mechanic for diagnosis.
ABS light and loud auditory warning whenever I drive the vehicle. We have replaced one of the ABS sensors on the front passenger wheel, since beating needed to be replaced to pass inspection. Still didn't help problem.
